JOINT FOR SHEET-METAL ROOFS.

T o all whom it may concern.'

Be it known that I, STEPHEN SCOTTON, of Richmond, in the county of Vayne and State of Indiana, have invented a new and Improved Joint-Cap and Fastening for Metal Roofs; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in forming a three leaved metal plate in the form of the letter T by soldering or by rolling iron-or other metal. The perpendicular part of this plate is fastened to the woodwork of the roof the edges of the meeting metal plates are turned up against the upright stem of this T plate. The top or cross piece is then bent down on each sidethus forming a waterproof cap or saddle joint and fastening.

T o enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A is the fro-nt wall, B, B, fire walls. C, C, ends of rafters or joists. D, metal plate extending from firewall to first joist and up the three edged wooden strip which is nailed on said joist (this part of the roof is laid on naked joists without sheeting) the turned up edge of metal plate D, is then nailed on the side of the said three edged wooden strip l. lThe three leaved metal blade E; an end view of which is shown at Figure 3, is then placed against the perpendicular side of strip l, to which it is nailed sidewise or the lower end of its stem CZ, Fig. 3, may be bent at right angles and nailed down through j oist C. The other three edged wooden strip 2, is then nailed firmly onto the top of joist C, and against the stem of E. Both of these three edged strips when nailed on the top of j oist forming one three edged or triangular strip as wide at its base as the thickness of the joist. The metal plate F, is then laid on-its edge extending up to the apex of strips 1, and 2, on the side of the latter it is nailed. The top cross piece of E, (see g, g, Fig. 3,) are then bent down on each side (they may have been turned up previously to facilitate the nailing). l/Vhen the ends g, g, are bent down the joint is finished and water tight.

Fig. 4 shows the cap and stem with one three edged strip on and a nail 3, driven through stem into the strip sidewise.

Fig. 2, is a side view of E. n, is a notch cut out of the stem to let it bend over the comb of a roof. m is a piece cut from the stem to enable it to lap over another piece of E-p. C shows the same cap fastening as Fig. 3, for metal plates when laid on sheeting. The meeting edges of the metal plates 0, 0, see Fig. 5, are turned up high enough for a. water oint. Fig. 3, is nailed down onto sheeting-and theends, z', are bent down over the upright edges of o, 0, and afterward crimped or set by means of pincers as at C, or by hammering-thereby forming a tight water joint and also securing the metal plates firmly to the roof. 3, 4, 5 show the joints of metal plates on the comb of roof. They are hooked joints hammered tight and may be filled with cement of any kind. This roof may be made as flat as any known roof or assteep.

AThat I claim as my invention and desire to secure by Letters Patent is- Forming a three leaved metal plate shaped thus, T, by soldering or rolling iron or other metal-for securing the joints of metal roofs-substantially as herein set forth.
